I’ll throw in my thoughts. I was thinking the other day (never a good thing after several glasses of wine) of how many air forces need a small, economical, robust and easy to maintain point defense fighter. I’m not talking about a multi-roll like the JF-17, but a simple point defense fighter to replace the many F-5E and MiG-21/J-7 aircraft out there.
My though was a modified Hongdu L-15 in a single seat configuration (similar nose configuration as the Hawk 200)? This aircraft would be in the same class as an (updated) F-5E and would serve well as a point defense fighter and can patrol for airspace violations and provide valuable flight hours for pilots.
